Group of local snowboarders were lapping the Tele Bowls on 1/19. Roughly a dozen people had been down the (skier's) left Tele Bowl when around 4pm a rider traversed from the top of the bowl out to the skier's left side and triggered a 30"+ slab which spanned the skier's left side of the bowl. The slide failed at the rider's feet, and so he was not caught or buried, and no one else was on the slope at that time. The slide ran about 3/4 of the way down the bowl, and the debris near the bottom was estimated to be about 2.5' deep.

The group was comprised of some experienced individuals, atleast 2 who had AIARE level 2 certs. The group had discussed the potential of a touchy snowpack, dug a pit previously in the (skier's) right Tele Bowl and didn't find any significant signs of instability, but did not assess stability in the left bowl. This slide is very similar to the one triggered by another party the day before in a similar location (see https://www.esavalanche.org/content/skier-triggered-avalanche-punta-bardini) which went on buried surface hoar and is a good reminder that instabiity can lurk even a couple days after a storm on persistent weak layers such as these.
